Which detail from the excerpt best develops the idea that Edward is a savvy businessperson, even as a young boy?

(11) Transportation, in those days in Brooklyn, was by horse-cars, and the car-line on Smith Street nearest Edward's home ran to Coney Island. Just around the corner where Edward lived the cars stopped to water the horses on their long haul. The boy noticed that the men jumped from the open cars in summer, ran into the cigar-store before which the watering-trough was placed, and got a drink of water from the ice-cooler placed near the door. But that was not so easily possible for the women, and they, especially the children, were forced to take the long ride without a drink. It was this that he had in mind when he reserved his Saturday afternoon to "play ball."

(12) Here was an opening, and Edward decided to fill it. He bought a shining new pail, screwed three hooks on the edge from which he hung three clean shimmering glasses, and one Saturday afternoon when a car stopped the boy leaped on, tactfully asked the conductor if he did not want a drink, and then proceeded to sell his water, cooled with ice, at a cent a glass to the passengers.
